Assembled from klammertext-dev ed13dfaa5b7a. kpy/klammertext.cpp is a
CPython extension module giving a Python script an instance of the
Machine class -- ktext in-process, set up through the same functions the
command uses. Errors map one-to-one to Python exceptions under the C++
names; an @eval's Python exception is chained as __cause__. Built by
make -C mac, found through PYTHONPATH (env/runtime.env sets it), tested
by tst/kpy_test.sh. Three engine changes came with it: Error::message(),
set_command_state(), and the @eval error report carrying its traceback.

A character written in the ^...^ mnemonic form -- ^oe^, ^zz^, ^hello^ --
used to kill ktext outright: no message, no output, and an exit status
that looked like a crash because it was one. Only the forms that happen
to spell hexadecimal digits escaped, and they were right by luck rather
than by reading. Any caret form that names no character is now a located
error that quotes what was written.
A klammer may now sit inside square brackets and braces as it already
could inside parentheses, and may be followed by the punctuation that
ends a sentence: [@i word@], {@b word@}, @i word@'s. The rule is a fixed
list of characters, because none of them can occur inside a klammer name
and so none of them is ambiguous next to a delimiter. A letter still
cannot: "x@" is the named closing delimiter, so a letter before "@" has
two readings and no rule can separate them.
The abbreviations an author writes -- the hyphen form @i-word, a klammer
glued to its neighbouring punctuation -- are now recognised as author
conveniences only. They are not applied to @@ definitions or @@@ system
commands, which are written by someone who needs no such shorthand and
whose forms are already whole.
Also fixed, each of them silent: an exported shell function in the
environment broke every @eval in the document; a line break written with
@nl was destroyed when it passed through a klammer that generates a
table, printing as \textbackslash{}newline in the finished PDF; and
"kdesc --coverage" shortened its file column by comparing the spelling of
a path rather than the path, so a klammer set reached by a symbolic link
showed a full path where its neighbours showed a short one.
New in the distribution: ref/, a small klammerset that describes the
Klammermachine's own tables in Klammertext. It currently provides the
character tables -- the diacritics and the extended Latin letters -- as
klammers that render to any target, so the documentation of what can be
written cannot drift from what the machine accepts. It is early, and
will grow.
The Klammertext taxonomy now has a section on targets, describes the
@@@klammerset system command alongside the other three, and states the
precedence of "^" -- what a caret means before a letter, a digit, a
punctuation character, and a quote, in one ordered list.
(from dev 6594c7ff8c1f)
kdesc gains --coverage, which reports for every klammer the set of targets it
can render to, and — the point of it — which klammers' coverage cannot be
derived and must therefore be declared. Three rules: coverage is DERIVED
where the definitions determine it (a general body of klammer calls covers
the intersection of what those klammers cover, by a greatest fixpoint after
loading), DECLARED where the engine cannot interpret what decides it (an
@eval body, whose targets are undecidable), and UNKNOWN where nothing is
written — which never means "deliberately unavailable".
Two new spellings in a definition's name. A comma-separated target list,
"@@table.html,tex :: ...", gives one body several targets; it is surface
syntax, expanded at registration, and each member goes through the
redefinition rules on its own. And "@@date.* :: ..." writes the general
target out, asserting that the klammer works for EVERY target including ones
not yet defined — a stronger claim than a list of the targets defined today,
and the one target declaration that could be mechanically falsified.
The Standard Klammer Set was swept accordingly: it now has no general
definitions at all, every klammer names the targets it serves, six use ".*",
and tex and pdf are at zero undecided.
kdesc's flags are reorganised on two rules: a flag reached for often gets a
single letter (-k klammers, -t targets, -c characters, -i input), a more
specialised topic a multi-letter name (--argtypes, --katoms, --rewrite,
--optionsets, --coverage, --klammerset, --font); and -v says how much to show
about PROCESSING, never what the RESULT contains — so the katom regex column
is "--katoms full" and the coverage detail "--coverage all". NOTE: "-k" now
lists klammers (optionally filtered by a name/description search); the katom
table moved to "--katoms".
Fixes carried along: an option written with no value crashed the command with
SIGSEGV instead of reporting the mistake; two required positional arguments
never parsed; kdesc and kdiag printed an error and exited 0; and definition
diagnostics counted registrations rather than what was written, so one line
could be reported as two definitions and then printed twice.
Four new test suites: target_list, coverage, command_option, kdesc.
(from dev 46f54080bd9a)
A named group of optional parameters, declared once and used by several
klammers, so a writer learns one vocabulary instead of a spelling per
klammer. The "o" target is a pseudo-target beside "k": "k" declares a
klammer's interface and documents it, "o" declares an option interface and
documents it, and neither produces output for any target.
@@caption_args.o :caption :number.bool true :caption_side.side
: Arguments that define a caption for a block element @@
@@code.k :filename @hpos_args :hpos left @ @caption_args :caption_side top @
| text.literal : A source file displayed verbatim @@
A set is used only in the parameter list of a ".k" declaration -- the one
place a klammer's interface is declared once for all of its targets -- and
is resolved as that list is read. Names and types come from the set; a
default may be overridden where it is used. A klammer application in a
parameter list is now a definition-time error.
The SKS gains the sets caption_args and hpos_args (:hpos and :offset), and
@table, @image, @image_grid, @reference and @show gain .k declarations. A
distance is no longer written as a position: :hpos 4em is rejected, and the
same layout is :hpos left :offset 4em. Code listings are numbered by
default, like tables and figures.
New engine sources mac/option_set{,_registry}.{h,cpp}; tst/ ships two more
suites, option_set_test.sh and signature_test.sh (twelve in all).
(from dev 34e536cb0329)
A klammer that reaches itself, directly or through a cycle, expanded
until the C++ stack was exhausted: the process died from SIGSEGV with no
message and no location. The former limit guarded only the top-level
fixed-point iteration, never the descent through klammer application. A
depth guard now raises a recursion error naming the klammer and where it
was applied. The same loop's termination test moves from "the katom list
stopped growing" to "a pass applied no klammer", since a klammer whose
body expands to nothing is a reduction that adds no katoms; exceeding the
round limit is now an error rather than a message followed by rendering a
document with live klammers still in it.
ktext --check locates every klammer application written in a document or
in a klammer body and checks name existence, argument count, option
names, and target coverage without applying anything, reporting all
problems at once. This is possible because Klammertext has no catcodes:
katom structure is fixed when a file is read, so a klammer body has a
determinate shape before it is expanded. The check therefore reaches what
the engine cannot -- the branch of a @cond that is not selected, and
bodies a given render never enters.
@cond's set of truth values is an open language question, so its meaning
is unchanged here; an unrecognized predicate now warns, giving its value
and location.
tst/ gains recursion_test.sh (7 cases) and check_test.sh (19 cases), and
this snapshot's test Makefile is generated from the shipped suite list so
the two cannot drift apart.

The @@@klammerset system command formally declares a klammerset — a
named, logically related group of klammer definitions — with an
operative, idempotent declaration (:requires and :files load in order
at the declaration point, relative to the declaring file). A bare
symbol given to ktext -k, kdesc --input, or :requires resolves to
x/x.k on the search path: the document's directory, then
KLAMMERTEXT_KLAMMERSETS, then KLAMMERTEXT_HOME; kdesc --klammerset
lists the available sets. sks/sks.k is the first declared klammerset,
so `-k sks` loads the SKS by name. The engine's lookup classes were
renamed *_set → *_registry to keep the two concepts apart, and the
whole C++ tree now follows standard const-correctness conventions.
tst/ gains klammerset_test.sh (18 cases).

Sync with klammertext-dev through b90b0e09:
- Argument types end to end: :python_cast values are applied (Python
@eval receives real bools/numbers/lists), argument values are
validated against their argtype patterns with the argtype's
description as the error message, argtypes can declare :default
(overridable per declaration), and parameterized type families are
supported: rest(N) casts a rest argument to an N-dimensional list
(bar-count = dimension).
- Unified indexed_range syntax (selector with parenthesized subsets,
composable mnemonic names) for table lines and spans.
- Table klammer: caption fonts fixed in both targets, :column_width /
:leading / :colsep wired, :colspan and :rowspan render (HTML
attributes; \multicolumn / \multirow), calculated cell values (:calc)
with prefix operators, display-precision semantics, :calc_format and
:decimal period|comma.
- Fonts: closed-world resolution on the Klammertext font store
(infrastructure in mac/font_store; no Google Fonts links or fetch).
Default fonts live in the top-level fnt/; additional fonts install
into KLAMMERTEXT_FONTS directories via kdesc --font (list, samples,
preview, install — classification by font metadata). CSS font family
names are quoted (digit-initial families were silently lost).
- Environment files moved from mac/env/ to the top-level env/; shell
profiles source env/runtime.env. Dead per-host variants removed.
- Container: fnt/ ships in the image; curl removed (no network use).
Curated source subset assembled by klammertext-dev's doc/make_dist.sh: the Klammermachine (mac), the Standard Klammer Set (sks), the commands (com), editor plugins and install guides (doc), a test subset (tst), and lib/bin placeholders. Builds with 'make -C com'.
